Next steps for battery diagnostics

Batteries are a cornerstone of expanding sustainable infrastructure. Battery behavior has an impact on consumers recharging their electric vehicles, industries designing battery-powered equipment, large-scale electric grid performance, warranties for electronics, and safety for everyday users. Correctly planning, executing, and succeeding in battery deployment relies on an accurate understanding of how batteries function and fail. We sought out researchers on the leading edge of battery diagnostic and prognostic techniques to describe where the field is headed. In this Voices piece, they provide their expert opinions—including evolving definitions, data as a key resource, future battery formats, and diagnostics motivating industry investment—to portray the future of battery diagnostics and prognostics.
